Amashubhu Ahlanganisiwe vs. Ahlanzekile Ngogesi: Yikuphi Okungcono Ohlelweni Lakho?
ukuhwebelana okubalulekile okuzokusiza ukuthi unqume.
Okugoqekile vs. Okucwebezelisiwe ngogesi: Umehluko Obalulekile
Isici | Ipayipi Eligoqekile | Ipayipi Eligoqwe Ngogesi (EP) |
Ukungasebenzi ngamakhemikhali | Kuhle kakhulu. Kwakha umgoqo ongasebenzi, ongenansimbi. Kuqeda ukumuncwa kwezinto ezibuthakathaka ezihlaziywayo njenge-H₂S ne-MeSH. | Kulingene. Kushiya insimbi eveziwe, engase isabele futhi ibangele ukwehla kwezinga noma ukulahleka kwezinto ezibuthakathaka ngokuhamba kwesikhathi. |
Ukumelana nokugqwala | Kuhle kakhulu. Ukugoqwa kwe-silicon kusebenza njengesithiyo; kunikeza ukuvikelwa okungaphezu kokuphindwe ka-100 kune-EP kwamanye ama-asidi (isb., i-HCl engu-5%). | Kuhle. Inqubo icebisa indawo engaphezulu nge-chromium oxide, ithuthukisa ukumelana nokugqwala ngaphezu kwensimbi engalashwa. |
Ukungathandi amanzi nokoma | Kuhle kakhulu. Amandla aphansi obuso anciphisa isikhathi sokomiswa komswakama ngamaphesenti angafika ku-50 uma kuqhathaniswa ne-EP, kunciphisa isikhathi sokuphumula kohlelo. | Kubi. Indawo enamanzi amaningi igcina umswakama isikhathi eside, okuholela ekomeni kancane nasekuphazamisekeni okungenzeka kwamanzi. |
Izindleko Nesikhathi Sokulethwa | Okuphansi Nokusheshayo. Ngokuvamile kungabizi kakhulu ngemitha ngayinye futhi kungaqhubekiswa emasontweni ama-2-3. | Phezulu futhi Kancane. Inqubo ebiza kakhulu evame ukubambezeleka ngenxa yokulibaziseka kokuthunyelwa kwezinto. |
Imikhawulo Yomzimba | Imikhawulo Yobude: Izinti eziqondile zingafinyelela ku-80 amaintshi; Amakhoyili ubukhulu obungaphandle 18-36 amaintshi. | Imikhawulo Embalwa. Ingasetshenziswa kubude obude kakhulu bamashubhu ngaphandle kwezithiyo ezibonakalayo. |
Ukucubungula Okwengeziwe | Ingagoba ngemva kokumbozwa uma kulandelwa imihlahlandlela; ukushisela kucekela phansi ukumbozwa endaweni ethintekayo ukushisa (~2-4mm). | Ukushisela kudinga ukuphinda kwenziwe i-passivation noma ukuhlanza ngemva kokushisela ukuze kubuyiselwe ukumelana nokugqwala. |
Imibuzo Ebalulekile Yokuqondisa Ukukhetha Kwakho
Ukuze wenze isinqumo esifanele, cabanga ngezici ezintathu ezibalulekile:
· Uyini umdingo wakho wokuzwela? Kokuhlaziywa kwamazinga okulandelela (izingxenye ngesigidi/izingxenye ngetriliyoni) okubandakanya amakhemikhali asebenzayo noma akhangayo (isb., isulfure, i-mercury, i-ammonia), amashubhu amboziwe angcono. Izindawo ze-EP zingakwazi ukumunca la makhemikhali, okuholela emiphumeleni engalungile nokulahleka kweziqongo.
· Yiziphi izithiyo zakho zomzimba? Uma uhlelo lwakho lusebenzisa amashubhu agoqekayo amade ngaphezu kwamafidi ambalwa noma izinti eziqondile ezingaphezu kwamasentimitha angu-80 ubude, i-EP iyona ekhethwayo ngokwejwayelekile. Amashubhu aqoshwe ngokupheleleyo anomkhawulo ngosayizi we-reactor, kanti i-EP ayinayo imikhawulo yobude.
· Liyini uhlelo lwakho lwesikhathi nesabelomali? Ukugoqwa ngokuvamile kunikeza ukonga okungu-50% noma ngaphezulu kanye nezikhathi ezimfushane kakhulu zokulethwa uma kuqhathaniswa ne-electropolishing. Uma isivinini nezindleko kuyizinto eziyinhloko, amashubhu agoqiwe ngokuvamile ayikhetho elingcono.
Iminikelo Ebalulekile Yobuchwepheshe
· Indawo “Ephakeme Kakhulu”: Ezidingweni eziqinile kakhulu zokungasebenzi, isixazululo esifanele ukufaka ukugoqwa epayipini elihlanjwe ngogesi, nakuba lokhu kuziza ngezindleko eziphezulu.
· Ukucatshangelwa Kokushisela: Uma ukushisela kudingeka, ukugoqwa kungcono ukuthi kwenziwe ngemva kokushisela ukuze kuqinisekiswe indawo eqhubekayo, evikelwe kuyo yonke indlela yokugeleza.
Umthetho Olula Wokukhetha
· Khetha Amapayipi Agoqiwe ezinhlelweni ezihlanzekile, ezinomuzwa ophezulu njenge-chromatography, ukulethwa kwegesi kwe-semiconductor, noma ukukhiqiza kwezemithi lapho ubuqotho bedatha nokomiswa okusheshayo kubalulekile.
· Khetha Ipayipi Eligoqwe Ngogesi (EP) ezinhlelweni zezimboni ezigijima isikhathi eside, ezinokugeleza okuphezulu lapho ukungasebenzi ngamakhemikhali okwedlulele kungesikho okuyinkinga enkulu, noma lapho ubude bomzimba bungenza ukugoqa kungasebenzi.
Ngithemba ukuthi lokhu kuqhathanisa okunemininingwane kukusiza ukuthi wenze isinqumo esingcono kakhulu sohlelo lwakho. Uma ungabelana ngezinto ezengeziwe mayelana nokusetshenziswa kwakho okuthile (isb., ama-analytes ahilelekile noma ukucushwa kohlelo), ngingakwazi ukunikeza isiqondiso esiqondile kakhulu.
